Our website development expertise
Custom Next.js / React site
Built in Next.js, React and Tailwind, no template or page builder: every component hand-coded for green Core Web Vitals.
Pixel-perfect design build
Faithful build of your Figma mockups, responsive from mobile to widescreen, with spacing, states and transitions kept pixel-perfect.
Headless CMS & components
A headless CMS wired to the site: collections, structured fields and reusable components to manage your content without touching code.
Animations & micro-interactions
Advanced animations (GSAP, WebGL, Framer Motion, scroll transitions), built for visual impact without degrading your Core Web Vitals.
API & third-party integrations
Connected to your tools via API: Stripe payments, booking, CRM, email and AI building blocks, with business logic handled server-side.
SEO & GEO built into the code
Semantic markup, Schema.org structured data, metadata, sitemap and robots.txt, green Core Web Vitals: SEO is built in from the start.
Redesign & migration, no SEO loss
Migration from any CMS (WordPress, Wix, Shopify and more) with a 301 redirect plan: the traffic and authority you earned are preserved.

the site that changes everything?
A call with one of our web developers to answer all your questions about how we work.
Contact usThe questions we get asked the most.
The price of a custom website depends on its scope: number of pages, features, integrations and level of design. A showcase site costs less than an e-commerce store, because it needs less development. We prefer to quote honestly after a first conversation: our price benchmarks are on the pricing page.
Plan for 6 to 12 weeks depending on the scope. A showcase site ships faster than an e-commerce store, which needs a catalogue, payments and integrations. We give you a precise timeline from the scoping phase, with clear milestones.
WordPress is fine for simple needs, but it quickly piles up plugins, which slows the site down, weakens security and creates technical debt. A custom-built site gives you better performance, controlled security and the freedom to evolve every detail. For a project meant to last and rank well, custom remains the most solid choice.
We build custom with Next.js, React and Tailwind CSS. These modern technologies deliver fast, secure sites that are easy to evolve and natively optimised for search. Depending on the project, we add a headless CMS so you can manage your content on your own.
SEO is built into the code, not bolted on afterwards. We target the best Core Web Vitals scores (fast loading, optimised images), with semantic markup, structured data and a clean sitemap. The result: a site that pleases Google as much as AI answer engines.
Yes, as long as the migration is planned ahead. We keep the content that performs and set up a redirection plan to pass the authority of the old URLs to the new ones, otherwise traffic drops. This is the core of our redesign method, backed by our SEO and GEO offer.
You get 30 days of post-launch support to fine-tune whatever needs it. After that, our Maintenance & Growth offer takes over to evolve the site: new pages, features, continuous optimisation. You keep a dedicated contact and clear turnaround times.
The site is 100 % yours, and you can retrieve the source code. No lock-in to a proprietary platform and no license that traps you: you stay free to host it and evolve it wherever you want. It is your asset, not ours.
